Application filed September To all whom it may concern:

' Be it known that I, HUGH DOUGLAS More RAY, of 22 Langlands Road, Govan, Glasgow, Scotland, a subject of the King of 5 Great Britain, have invented certain new and useful Improved lVindow Fittings, of

which the following is a specification.

- The presentinvention relates to improved window fittings for sliding-sash windows arranged to open inwardly.

One object of the present invention is to arrange that while both of the two sashes which are usually provided move inwardly only one need be hinged and in accordance with this invention a bracket is provided adapted to be mounted on the two sashes to connect the two sashes so that they will move together.

Another object is to obviate a disadvantage that exists to such fittings at present in use in the fact that each window has to be fitted with numerous and comparatively eX- pensive parts by reducing the number of such parts as are usually permanently attachcd to each window and to provide other parts which may be moved from window to window when desired. lVith this object in view a window fitting according to the present invention comprises a bracket adapted to be detachably mounted on the two sashes to connect the sashes so that they move together. Further, in combination with this detachable bracket, a hinge may be provided adapted to be detachably mounted on the window frame and on one of the sashes so that both the bracket and hinge can be removed and applied to any one of a number of windows. Preferably means will be provided to permit relative movement between the two sashes when thus connected.

The various features of the invention will now be described with reference to the accompanying drawings but it is to be understood that this is by way of exemplification and not of limitation.

In the drawings:

inwards and the upper sash lowered and attached to the lowersash;

Fig. 2 is a plan, partly in section, of the window shown in Fig. 1;

Fig. 8 is an elevation to an enlarged scale of the hinge shown in Fig. 1;

Fig. 4 is a side sectional elevation to an enlarged scale of the attaching bracket shown in Fig. 1; i

Fig. 5 is a front elevation of the bracket shown in Fig. 4c. 7

Fig. 6 is a plan of the bracket shown in Fig. 5;

Fig. 7 is a side elevation of the cord attaching clip; and

' Fig. 8 is a front elevation of the clip shown in Fig. 7.

Referring to Figs. 1 and 2, the lower sash 1 of a window is provided with two hinges 2 which are attached to the window frame and the lower window sash so that the lower sash can move inwardly, it being understood that the beading 11 must be re moved for this purpose, this beading being preferably held in position by means of a clove-tail 12 and a screw and butterfly nut 13. The lower sash 1 is pulled inwards to the position shown indotted lines in Fig.

2 and the sash cord is removed and attached to a hook or other fastening at the side of the window in a manner to be here inafter explained. The window is now open and swings upon the hinges 2 so that the outside can be cleaned.

In order that the top sash 21 of the window may also be swung inwards for cleaning, the following apparatus is used Two studs 22 (Fig. 1 are driven into the top surface of the bottom sash 1, the upper parts being threaded and provided with butterfly nuts 23. Each of these studs 22 is provided with a bracket 24 which is held in position by the nut 23, the stud 22 passing through a slot 25 (Fig. 6) in the base of the bracket so that the bracket can be adjusted inwards and outwards to suit different widths of sashes. At the outer side of the bracket is an upstanding flange 26 (Figs. 4 and 5) in which is a right angled slot 27 opening upwards. In the consash 1 as shown in Fig. 1 and the 'topsash' 21 is then lowered untiltwo flateheaded screws 28 on the inner side of the top bar of the sash 21 drop into the vertical portions of the right-angled slots 27. In this position the weight of the top sash 21 is taken by the bottom sash 1. The two sashes are then swung inwards together and In or--.

the top sash-is ready for cleaning. der to clear the frame of the window, the top sash .21 must. move relatively 'tothe bottom'sash 1 to a slight extentand it is able to do-this by reason of "the horizontal portions of the right-angled slots 27,. since the heads of the screws 28 can slide-along the bottom portion of the slot 27.-as indicated in F ig..5. The slots 27, instead of being right-angled as shown, might bein -a curve or in a straight line sloping in-. wards and downwards from the top of the flange of the bracket.

As shown in Fig. .3 the hinges are each formed of two plates 3 and 4 hinged together by a pin in the ordinary.

way. The plate-3 has two holes'G each large enough to take the head of a screw 7 and each having at'its upper side a recess 8 so that when the plate is placedupon the screws 7 it can be moved downwards and the shanks of the screws will be located in the recesses 8, the plate being held in position by the heads of the screws. The plate 4 has in its upper position an open-mouthed slot 9 for a purpose which will appear. 'In. the actual construction the-recess 8 and the open-mouthed slot are. duplicated at 8 and 9 so that the same hinge may be used in eitherside of a window.

In operation four snap-headed screws 7 are driven into the frame of the window at suitable points to within a quarter of an inch of their heads and the plates 3are then placed over the heads of-the screws 7 and moved downwards until-they are held in position by the heads. The lower sash is next lifted a few inches and two screws 104 are driven into the sash in such-a position that when the sash is thereafter moved slightly downwards, the heads of these screws 1O will enter the open-mouthed slots 9 and will be supported by the plates '4. For holdingthe sash cords and permitting them to lee-readily disconnected from the sashes, a novel clip is used. This consists of a plate 41 (Figs. 7 and 8) having a flange 42 at right angles. The cord 43 passes through a hole in the flange 42 and is held in place by a knot in the normal fashion. The plate 41 is provided with an aperture 44-having atto p and bottom a recess 45 into which the shank of a screw 46 is adapted to pass, the screw being'fixed into the side of the sash.--'Thenitheiwin'dow 1S swung open,

the plate 41 is pulled downwards so that the head of the screw 46 can pass through the aperture 44 and the plate and cord are thus removed; the plateis then slipped over the head of a similar screw upon the outsideof the window zframe where itis held inposi- .tio'n untilcit risonce more required to be placed-upon the sash.
